File Shredder is a program to split a large file into smaller files. You can specify either how many pieces to split the file, or how big (in KB) to split the file. You have the option of filling the entire disks, which is convenient if you would like to split a file into multiple floppy disks. When File Shredder splits a file, it automatically generates a DOS batch file that will be used to combine smaller files into one big file. Since it is a normal batch file with DOS commands inside, you can combine files together in any PCs without installing any programs–not even File Shredder. Of course, the batch file works under a Windows 3.1 machine,a Windows 95/NT machine or even an old MS-DOS machine.
The File Shredder program can be downloaded for free.
